SraB -E rIneUIsHEn AND SMOKE-CONSUMER.

To all whom it may concern:

guisher and Smoke-Consumer, of which the following is a specification.

Our invention relates to an attachment for-locomotive smoke stacks which will effectively prevent. sparks being blown from the stack and which will consume in a large degree the smoke issuing therefrom.

provide an apparatus of the class indicated in which the amount of water used to extinguish the sparks and consume the smoke will be dependent upon the locomotive throttles position.

With the foregoing and other objects inview which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construct-ion hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed,'can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof,Figure 1 is a view in elevation with parts broken away showing a portion of a locomotive upon which is mounted our improved spark extinguisher and smoke consumer. Fig. 2 is a detail plan view of the spraying ring, and Fig. 3 is a cross sectional view on the line A.A of Fig. 2. Fig. 4 is a view illus trating the manner in which the locomotive throttle simultaneously controls the movement of the locomotive and the supply of the spray.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 10 represent-s a locomotive boiler of the usual type and construction and is provided at its forward end with the smoke stack 11, at the upper end of which is fastened the spraying ring 12, which ring is connected to the boiler 10 by means of the pipe 18. This pipe 13 enters the boiler at a point 20 which is below the normal water level in the boiler. The spraying ring 12 is formed of a pipe bent to conform with the inner periphery of the smoke stack, and is formed from metal Specif cation of Letters Patent. 7

' especially designed to withstand such con- Be it known that we, PATRICK MULLOYg and HENRY FIRMINHAC, citizens of the United States, residing at Mercer, in the county of Iron, State of Wisconsin, have; invented a new and useful Spark-Extin-I diftions as are met with at the upper inner edge of a locomotive smoke stack. Apertures 14 are formed in the walls of this ring and extend obliquely to the plane of the ring so that the water as sprayed therefrom will tend to move in a central and down- .ward direction. A T 21 is fastened to the two ends of the said ring and one arm thereof extends through theside walls of the locomotive stack and communicates with the pipe 13.,

; Connected to the boiler is a supply valve One of the'objects of our invention is toi 16, a controlling valvel? being positioned a slight distance above the valve 16 and is connected to and actuated by a lever 18. The lever 18 is connected by a link 23 to a bell crank lever which latter is arranged in i the path of'movement of and actuated by the locomotive throttle valve 22. In this connection it is to be noted that as shown in Fig. 1, as the throttle valve lever 22 is moved to open the throttle valve 24, the valve 17 will also be opened. A third valve 19 is provided to regulate the supply of water to the spraying ring and. is designed to he set and when once set is designed to remain always in that position. The supply valve 16 is designed to be closed at the end of each run of the engine.

It is known that the number of sparks and the amount of smoke issuing from the stack will depend upon the throttle position as the steam from the cylinder is exhausted into the stack. Therefore by connecting the throttle with the controllingvalve 17, the greater the amount ofsmoke and number of sparks issuing from the stack, the greater the amount of water that will be supplied to the spraying ring.

A shield 15 is secured to the upper end of the locomotive stack and is frusto-conical in shape and this shield insures that no live sparks will be allowed to issue from the smoke stack. This shield necessitates that the smoke and sparks issue from the center of the stack and it is at the center of the stack that the spraying ring most effectually sprays. From the foregoing it will be seen that we have designed a most efficient and durable spark extinguisher and smoke consumer.

What we claim to be new and original with us is 1. The combination with a boiler, a smoke stack, and a throttle, of a spraying ring attached to the said smoke stack, a pipe communicating therewith and with the boiler below the normal water level thereof, and means actuated by the said throttle controlling the amount of water supplied to said spraying ring.

2. In an apparatus of the class described, the combination of a smoke stack, a boiler, a throttle, a spraying ring secured to the inner surface of said smoke stack, a pipe communicating therewith and with the boiler below the normal level thereof, a supply valve in said pipe, a regulating valve in said pipe, and a controlling valve in said pipe secured to and actuated by said throttle.

3. In apparatus of the class described, the combination with a locomotive stack, a locomotive boiler, and a locomotive throttle, of a ring arried by theupper inner edge of the said stack and provided with a plurality of openings extending therethrough, a pipe communicating with said ring and with the locomotive boiler below the water line of the latter, a supply valve located in said pipe adjacent the boiler connection thereof, a controlling valve located beyond the said supply valve and actuated by and in conjunction with the locomotive throttle, and a regulating valve located beyond said controlling valve.

4:- In apparatus of the class described, the combination with a locomotive boiler, a smoke stack, and a throttle, of a frusto-conical shield secured to said smoke stack at its upper end, a spraying ring disposed within and housed by the said frusto-conical shield, a pipe communicating with said ring and with the locomotive boiler below the water line thereof, supply, controlling and regulating valves located in said pipe, and the said controlling valve actuated by and in conjunction with the locomotive throttle.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.
